exclusive interview. rich? >> reporter: well, david and liz, the questions surrounding the romney/ryan campaign now is basically why they're not doing any better. you've got a weakened president, eight percent plus unemployment, and you see the president beginning to show momentum here in the key state of ohio, down in florida. ryan basically tells fox business that eventually voters will start to see how bad the economy is, and they'll begin to come around to romney and ryan. we also spoke about taxes, more specifically, governor mitt romney's taxes and his 14.1% effective tax rate. ryan says under their new tax plan that governor romney would actually end up paying more. ♪ >> our pro-growth tax reforms are to lower tax rates for everybody by plugging loopholes starting with people like mitt romney -- >> reporter: so he would pay more? >> yeah. here's how it works. higher income people can use lots of tax shelters to shelter some of their income from taxation. close those tax shelters, more of their income is subject to taxation, that allows us to lower tax rates for everybody.
